To a/ZZ wil/0m t wwty'aoncerift:

Be it known that I, JOHN A. MCCARTHY, a citizen of the United States, residing at St. .Ioseph, in the county of Buchanan and State of Missouri, have invented cert'ain new and useful Improvements in Self-Vaporizing and Gas- Generating Illuminating Devices;` and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in self-vaporizing lamps in which the liquid hydrocarbons are sufficiently generated into gas as they pass from the reservoir to the ignition-tube to ignite without the aid of a separate heating device, the heat from the llame after lighting completing the vaporization and generation and securing a brilliant light.

I attain my object by the mechanism illustrated in the accompanying drawings, in which- Figure lis a vertical section of a single lamp embodying my invention. Fig. 2 is a front elevation of a double lamp embodying the invention. Fig. 3 is a perspective of a perforated vaporizer. Fig. 4 is a section of the base of the gas-chambermand lower end of the cold-air tube. Fig. 5 is a perspective of the air-regulator, and Fig.6 is a section of a cap at the bottom of the regulator. i

Similar letters refer to similar parts throughout the several views.

My device consists of a tank A, with a float and valve space Band its iioat b and valve b, at the bottom of whichvalve-space there is a needle-point valve B'. An air-tube A extends through the tank to allow the iioat to .rise and fall, thereby causing a steady flow of the liquid and an equal pressure. The valve-outlet space opens into a mixing-chamber C, in which there is a vaporizer D, Fig. 3. This vaporizer is attached to the inside of the mixing-chamber. It is bottomless, and its top and side have minute perforations d d, except at the center of the top, which is provided with a solid raised plate D'. Just below the needle-point valve and outlet small glass or mica loopholes or Windows cc 'permit a viewof the liquid drops as they descend into the mixing chamber, thus affording means to determine their rapidity that it may be properly regulated. From the bottom of the mixing-chamber a conducting-pipe E extends and opens into a gas-chamber F. Extending vertically through the center Aof this gas-chamber is a cold-air supply-tube H,with its base at or below the bottom of the gaschamber and its top at the base of the lamp'- burner.` This cold-air tube is provided with a revoluble regulator II, Fig. 5. A section of tube h is fastened rigidly 'in the regulator at its top. "Ihereis a circular space between the'regulator and section of tube h from top to open bottom for admission of cold air,- and tube h is provided with openings h h in the side, corresponding with apertures in the side 'of cold-airtube H near its bottom. This section of tube h fits closely around cold-air tube H, and the amount of cold air admitted into said cold-air tube is thus easily regulated by a partial revolution of the regulator. A removable cap h2, Fig. 6, is adapted to form the base of said cold-air supply-tube H and the section of tube h.

My lamp is adapted to the use of the Welsbach or similar types of burners and is provided with a mantle carried and raised and lowered by a Wire t', saidwire being held in position desired by the use of a thumb-screw i. The burner being made of perforated material of right-cone shape, an equal llame for the entire surface of the mantle is produced. The base of gas-chamber F is provided with asbestos packing ff for the purpose of absorbing any of the liquid hydrocarbons which by any possibility may escape vaporization.

.A hot-air pipe or conduit J, with a checkdamper or valve having its upper end connected with the mixing-chamber C, has a roof K, of metal or any suitable material, rigidly attached to it's lower end, which roof at its apex closely encircles the lamp-chimney. An ordinary lamp-shade is carried by uprights 7c and by them is held fitted up close into the lower part of roof K and is also lowered or raised by them, they being engaged by thumb-screws k' la'. In the mechanism described it will be seen that a triangular space IOO ' ing and into which prongs N N are locked v of shaft,allows the lamp to be adjusted at is left between the outside ofthe lamp-Ghininey, the inside of metal roof K, and the top of the ordinary lamp-shade. This space encircling the chimney constitutes `a hot-'airA chamber L, it being heated by the heat emitted through the chimney. `This hot-air rises into mixing-chamber C through hot-air pipe J, its only way of escape. An adjustable shaft M is rigidly fastenedon the top 'of the4 tank for the purpose of supporting lny device from the ceiling and raising or loweringit. This shaft consists' of inner and outer sections and a shoulderM' to serve asa stop; when lowering the lamp. Two prongs N N are rigidly attached by riveting or otherwise to the top of the outerv shaft. On the top of the inner shaft there is a right-and-left hooksocket O, adapted to be attached to the ceilby raising the lamp and outer 'section of shaft -until said prongs are carried between the hooks and by thenmaking a half-turn of the lamp and outer section of shaft, thus carryingcsaid prongs into position to drop into the hook-socket. A thumb-screw p, inserted in the side of the outer section of shaft near its top and operating against the inner section any height desired. The tank having been supplied with liquid hydrocarbons and the lamp adjusted to a convenient height, it is only necessary to open valveB sufficiently to allow the liquid in the tank to pass out in drops'. These drops passing` separately, through mixing-chamber `C and striking upon the solid center plate D of vaporizer with considerable force are each broken into minute particles and sprayed over the vaporiz'er and being thereby exposed are vaporized into gas, which by the circulating air is drawn through conducting-pipe E into gas chamberl F. Within a period of about thirty seconds there is sufficient selfvaporized gas accumulated in the device to light'the lamp;y From this flame theair in hot-air'chamber L is at once heated and the dropping liquid as it drops is thoroughly vaporized by the hot-air circulation and abrilliant light produced. d i v What I claim, and desire to secure by Let- 1. In a self-vaporizing and' gas-generating illuminating device, in a combination, a mixing-chamber 4and. a vaporizer therein, ahotair chamber in approximately the samehorizontal plane with said mixing-chamber and vaporizer consisting of the space surrounding thechimney and within the metal roof,and the hot-air pipe making connection across fromV said hot-air chamber to said mixing-chamber, substantially as described. f
